Continental
X-King 29 ProTection (folding)

Details

Continental's X-King is a great all-around tire with a fast-rolling tread, an open lug design that hooks up whether it's muddy or dry, a high-volume casing for nice shock absorbancy and a smooth ride, and Conti's grippy and durable Black Chili rubber compound. The ProTection version also features their excellent puncture protection.

I recently upgrade to these tire from 2.25. These tires are extremely quiet and smooth. I feel no resistance when I am riding. i have put 50 miles on these on the road. I have not taken the tire off road, but looking forward to
